Title: Coated polyester shaped articles
IPC: C08G18/69
Filed: 1968-01-16
Abstract: 1,224,051. Polyester-polyurethanes. TEIJIN Ltd. 16 Jan., 1968 [16 Jan., 1967], No. 2390/68. Addition to 1,186,431. Heading C3R. [Also in Divisions B2 and D1] Polyester-polyurethanes are prepared by reacting an organic disiocyanate, an ethylene terephthalate polyester or ethylene-2,6-naphthalene polyester and a difunotional chain extending agent so that the portions of polyester constitute 1/6 to 5/6 of the weight of the polyester-polyurethane and the remainder of the polymer contains at least one ethylenically unsaturated bond per 500 of the molecular weight of the polyester-polyurethane. The reaction is preferably carried out in the presence of a solvent. The ethylenically unsaturated bonds are suitably introduced into the polyurethane using a diol having ethylenic unsaturation in place of whole or part of the difunctional chain extending agent. Suitable such diols are alkene diols, unsaturated polyesters or unsaturated polyethers having a low degree of polymerization, poly(diene) glycols, poly(diene) dicarboxylic acids, bis-epoxypoly(dienes) and polyisoprene dicarboxylic acids. Water dispersibility of the polyester-polyurethane may be improved by incorporating a tertiary amino group into the polymer and neutralizing such a group with an acid. In a typical example, polyethylene terephthalate copolymerized with pentaerythritol is dissolved in nitrobenzene together with a polybutadiene glycol and dibutyl tin dilaurate and to the resultant solution is added diphenylmethane diisocyanate to form a copolymer which is precipitated with methanol. The polyester-polyurethanes are used to coat polyester articles, which coated articles are adhered to rubber (see Divisions B2 and D1).

Title: Improvements in or relating to the control of alternating current electric supply circuits
Inventor: STEADMAN ERNEST JAMES
IPC: H05G1/56
Filed: 1955-02-02
Abstract: 792,112. Switching systems for X-ray apparatus. WATSON & SONS (ELECTROMEDICAL). Ltd. Feb. 2, 1956 [Fob. 2, 1955], No. 3065/55. Class 38 (4). A circuit arrangement for effecting closure of an X-ray contactor 19 at a zero voltage point in the A.C. supply wave comprises a half-wave rectifier 3 and normally-open contacts 4 of a control relay 5 connected in series with the operating coil 1 of the contactor and a " prepare " switch 6 across an A.C. source 2, the relay being actuated, upon operation of an " exposure " switch 11, by a voltage pulse supplied to its winding from a peaking transformer 9 over a rectifier 13 which is so poled that the contacts 4 close during a half-cycle when rectifier 3 is non-conducting. Energization of contactor coil 1 is thus initiated at the commencement of the next half-cycle. Closure of contacts 19 follows a half-cycle later, as the operating time of the contactor is arranged to correspond to half a cycle. The contactor subsequently holds in, over an auxiliary contact which now short-circuits the rectifier 3, until relay 5 is released. In the form shown, the relay is polarized and is released by returning switch 11 to its " off " position to bring into circuit a further rectifier 12 which reverses the polarity of the pulses applied to the winding. In another arrangement an unpolarized relay is employed which, when operated, closes auxiliary contacts for short-circuiting rectifier 13 so as to retain the relay energized until the energization circuit is interrupted by the opening of a simple make - and - break " exposure " switch. The peaking transformer 9 is supplied through a resistor 7 by which the phase of the operating pulse applied to the relay is controlled. A phase change circuit, such as described in Specification 792,111, [Group IV (a)], may be incorporated, so that energization of the contactor may be initiated at the beginning of a half-cycle of either polarity. Specification 601,811. also is referred to.
